Description
Technical field
The utility model relates to technical field of motors, especially a kind of commutator.
Background technology
Commutator is parts in order to motor can be allowed to continue to rotate down on DC permanent magnet series-wound motor, when commutator is installed on motor, need to connect the commutator segment on commutator and enamelled wire and then be energized, enamelled wire is have enamelled coating outside conductor, traditional is use spot-welding technology, adopt special electric welding machine, utilize high pressure height electric current to make wire enamel melting layer so reach winding connect effect, in the process of spot welding, debugging is complicated, instrument height power produces energy consumption and easily produces electric spark and smog, thus waste source material, increase cost, and production efficiency is low, and the high pressure of spot welding, high electric current has certain damage to enamelled wire, affect the performance of commutator.
Utility model content
The technical problems to be solved in the utility model is: adopting spot welding to cause the problem that cost is high, production efficiency is low to solve when commutator segment and enamelled wire are connected on traditional commutator, now providing a kind of commutator.
The utility model solves the technical scheme that its technical problem adopts: a kind of commutator, comprise the column commutator matrix of insulation and be arranged on some commutator segments of described commutator outer surface of matrix, described commutator segment comprises the main body be arranged on described commutator matrix, one end of described main body is outward extended with hook, the one side that described hook is relative with described main body is provided with sawtooth, the conductor contact of described sawtooth and enamelled wire, the conductor contact of described sawtooth and enamelled wire, destroy the enamelled coating of enamelled wire by the sawtooth on hook and then reach the effect connected with winding.
In order to make sawtooth and enamelled wire better connect, further, the height of described sawtooth is greater than the thickness of enamelled wire enamelled coating.
Preferably, described hook is connected with enamelled wire riveting.
The beneficial effects of the utility model are: commutator of the present utility model is linked up with by riveting, the sawtooth on hook is forced to destroy the enamelled coating of enamelled wire, and then reach and connect with the winding of motor, avoid the high pressure of spot welding, high electric current to the damage of enamelled wire, and production efficiency is high, cost is low, between commutator and enamelled wire, conductive effect is good.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the vertical view of the utility model commutator;
Fig. 2 is A-A direction view in Fig. 1.
In figure: 1, commutator matrix, 2, main body, 3, hook, 4, sawtooth.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Embodiment 1
A kind of commutator as illustrated in fig. 1 and 2, comprise the column commutator matrix 1 of insulation and be arranged on some commutator segments of described commutator matrix 1 outer surface, described commutator segment comprises the main body 2 be arranged on described commutator matrix 1, one end of described main body 2 is outward extended with hook 3, the one side that described hook 3 is relative with described main body 2 is provided with sawtooth 4, the conductor contact of described sawtooth 4 and enamelled wire, the conductor contact of described sawtooth 4 and enamelled wire, destroy the enamelled coating of enamelled wire by the sawtooth 4 linked up with on 3 and then reach the effect connected with winding, the height of described sawtooth 4 is greater than the thickness of enamelled wire enamelled coating, described hook 3 is connected with enamelled wire riveting.
Operation principle:
Between the main body 2 enamelled wire being placed on hook 3 and commutator segment, by riveting hook 3, force the sawtooth 4 on hook 3 to destroy the enamelled coating of enamelled wire, and then reach and connect with the winding of motor, avoid the high pressure of spot welding, high electric current to the damage of enamelled wire, and production efficiency is high, cost is low.
Above-mentioned is enlightenment according to desirable embodiment of the present utility model, and by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
Claims (3)
1. a commutator, comprise the column commutator matrix (1) of insulation and be arranged on some commutator segments of described commutator matrix (1) outer surface, it is characterized in that: described commutator segment comprises the main body (2) be arranged on described commutator matrix (1), one end of described main body (2) is outward extended with hook (3), the one side that described hook (3) is relative with described main body (2) is provided with sawtooth (4), the conductor contact of described sawtooth (4) and enamelled wire.
